Have you ever seen a bird without feathers? All birds have feathers and birds are the only
animals with feathers. However, it would be inaccurate to use feathers a way of defining
birds. This is mostly because there were several non-bird dinosaurs that had wings. One of
these was the Caudipteryx. This species had wings but they were not sufficient for flying.
These extinct bird-relatives did use the feathers and plumage for many other adaptive
things. Such as insulation, breeding and camouflage.
